FIFA test goalline technology systems in Germany
Football's governing body FIFA has had two different systems tested at a Germany stadium as they look to introduce goal line technology into top-flight football.
Both 'Goal-Ref', a system which can verify whether a goal has been scored by using a chip in the ball, and 'Hawk-Eye', the camera system already used in tennis, were tested at the Duesseldorf Arena on Tuesday.
A number of factors were included to create realistic factors which could affect the system, with testers using smoke machines and strobe lighting to replicate different weather conditions.
"The goal-line technology will be tested for performance and reliability. There will be static and dynamic tests to stimulate day and night situations," said FIFA in a statement.
A decision on which system will be used is expected to be made at the International Football Association Board's (IFAB) next meeting in Edinburgh from March 1-3.
Goal-line technology was already in use at December's Club World Cup in Tokyo and is expected to be used at both the 2013 Confederations Cup and the 2014 World Cup in Brazil.
The new technology could be used in the Bundesliga as early as the start of the 2013/14 season in August.
